Microbiology I - STUDY GUIDE EXAM 1Bacillus - answer Rod shaped bacterium
Bacteriology - answer study of microorganisms called bacteria
Biology - answer study of all living organisms both plant and animal
Botany - answer study of plant live
Capsule - answer A slimy mucilaginous (mucous-gelatin like) coating outside the cell
wall
Cell membrane - answer A semi-permeable membrane found just inside the cell wall.
Serves to control the osmosis of substances into and out of the cell.
Cell Wall - answer It is responsible for maintaining the size & shape of a living cell. Also
serves as a reference point for describing the location of other cell parts.
Coccus - answer Spherical or round bacterium
Conjugation - answer A form of sexual reproduction utilized by bacteria
Cytoplasm - answer The semi-fluid material inside the cell
Diplobacillus - answer Two rod shaped cells forming a pair
Diplococci - answer Two Coccus shaped cells clinging together
Endospore - answer serves as a source of protection when environmental conditions
are not favorable for survival or growth. Such as in conditions of heat drying, poor
nutrient supply and chemical exposure.
Eucaryotic - answer microorganisms with a well-defined or "true" nucleus with a nuclear
membrane.
Fimbriae - answer(Also known as Pili) Found externally but extend through the cell wall
to attach to the cell membrane. Serves as a mechanism of attachment of the cell to a
surface. Serves to mediate a form of sexual reproduction utilized by bacteria.
Flagella - answerFound external of the cell wall they provide motility for the cell
, Germination - answerWhen the conditions for growth improve the Endospore will then
convert into a living, growing, vegetative cell.
Granules - answerInclusion bodies; Serve as a storage place for food reserves or as an
accumulation point for substances formed in excess of the immediate needs of the cell.
Immunity - answerThe condition in which protection either natural or acquired, is
obtained against disease causing agents.

Mold - answermulti-cellular Eucaryotic organisms. Reproduce by conidia or zygote
formation
Morphology - answerThe size & shape and arrangement of cells.
Mycology - answerThe study of fungi. (mold yeast)
Nuclear body - answerthe location of the bacterial DNA. It functions as the brain of a cell
it a carries the inheritable characteristics of the cell, it controls metabolism.
Pili - answer(Also called Fimbriae) - Found externally but extend through the cell wall to
attach to the cell membrane. Serves as a mechanism of attachment of the cell to a
surface. Serves to mediate a form of sexual reproduction utilized by bacteria.
Procaryotic - answerDo not have an organized nuclear body within a membrane.
Protozoology - answerThe study of single cell animals.
Ribosomes - answerThe site of protein synthesis. It builds the protein that are
necessary for cell growth and metabolism.
